The image originally was just a small on-line image that i found on the internet, that was only the size of roughly half the laptop screen,however ive changed its DPI to 2,500 through Irfanview,and its dimensions to 6,480 x 8,640.

When i open the image on my laptop with 'windows photo gallery' it just opens at the normal size that all images open at.(Roughly 2/3 size of the laptop screen)

Although if i open it with paint its huge, and freezes my laptop as its too big to show on the screen, plus looks very blurry in paint when it doesn't freeze! :9

If i send this image to canvas print company and tell them to print it onto canvas size 36x48inches,how good will the clarity be when i get the finished art canvas to my home??

Will it be the same clarity and quality in that size as how it looks when i open the image in windows photo gallery (photo 2/3 of screen size),OR,will it look very blurry and crap and look like how it looks when i open it with paint and it shows in my laptop screen at its full size dimensions??
